A CORPORATION OF WEST VIRGINIA TROLLEY WIRE GUARD` SUPPORT Applicationfiled December 23,1931. seran ne. 582.8261

of guard strips at opposite sides of mine` trolley wires, wherever thewire passes over a track or other passageway.

The principalxobject of the invention is to provide a uniquesupport ofsectional construction which may be quickly and easily applied to aconventional trolley wire insulator. v

Another object is to provide a novel structure in which the upper endsof hangers for the guards, are provided with `means for holding clampsections relatively assembled around the insulator. j

A still further object is to provide a construction of exceptionallysimple and inexpensive nature, yet'one which will be elfieient anddesirable from numerous standpoints.

With. the foregoing in View, the invention resides in the novel subjectmatter hereinafter described aand claimed, description beingaccomplished by reference tothe accompanying drawing.

Fig. lis a perspective view partly broken away and in section, showingtwo of the guard supports applied.

Fig. 2 is a vertical transverse sectional view on line 2 2 of Fig. 1.

Fig. 3 is an enlarged perspective view of one of the guard supports.

In the drawing above brieiiy described, IV denotes a portion of aconventional trolley wire for a mine, I refers to insulators whichsupport said trolley wire, G denotes the guards at opposite sides of thewire, and S has reference to supports for the guards G, constructed inaccordance with the present invention.` Two or more of these supportsare used for each pair of guards,

and as they are all of the same construction, a description of one willsuffice.

The support S comprises a clamp having a central yoke portion tosurround the insulator I, two arm portions projecting in oppositedirections from said yoke portion, `and two hangers H depending fromsaid arm portions' and adapted to support the guards G. In the preferredconstruction,

the clamp is formed from twol horizontally elongated bar-like sections10 having outwardly bowed, central portions 11 to jointly embrace theinsulator I, the portions of said sections 10 which project from thebowedportionsll, being disposed side by side and substantially incontact with-"each other., These ends ofthe sections 10 are snuglyreceived in links12 forming the upper portions ofthehangers II, so thatthe two clamp 'sections are held in assembled relation, engaged withthe" insulator I. Preferably, the upper edges of the clamp sections 10are formed with notches 18 which receive the links `12 and the portions14 at the outer sides of` these notches, constitute lugs which preventsaid links 12 from accidentally shifting from the clamp.

Each link `12 is preferably formed by* a metal stamping as shown, beingformed with an upper relatively `largeopening 15 and a lower smalleropening 16.` Theopenj i ings 15 of the `two links 12, receive vthe endsof the clamp sections 10, and the smaller openings 16 facilitateconnection of the low'-V er hanger sections 17, with the upper sectionsor links 12. Each section 17 may well be formed by a length of heavyinsulated wire anchored at one end in the opening 16 and bent tosurround the guard G.

In applying the clamp to the insulator I, the two clamp sections arepositioned so that their bowed portions 11 jointly surround saidinsulator, the link 12 of one of the hangers is engaged with the clampsections at one end of the latter, the other ends of these clampsections are then pressed together, and the link 12 of the other hangeris then engaged with them. The clamp is thus tightly heldupon theinsulator, and the hangers II may be readily connected with `the guardsG, by bending them around said guards and fastening their ends, asshown.

The guards, when supported by a number of the supports herein disclosed,serve ef-` fectively to prevent the heads of persons or animals walkingunder them, from coming in contact with the trolley wire Wand it will beunderstood that said guards may be mounted wherever advisable.

The details disclosed may be considered as preferred, but within thescope of the invention as claimed, numerous variations may be made.

I claim:-

l. A trolley wire guard support comprising a contractible clamp tosurround a trolley wire insulator, and guard-supporting hangers havinglinks at their upper ends for holding said clamp contracted.

2. A trolley wire guard support comprising a clamp to surround a trolleywire insulator, said clamp being divided into two sections adapted tojointly embrace the insulator, and guard supporting hangers having linksat their upper ends for holding said clamp sections in assembledrelation.

3. A trolley wire guard support comprising tw'o elongated clamp sectionshaving outwardly bowed portions between their ends adapted to jointlysur-round a trolley wire insulator, and guard-supporting hangers havinglinks at their upper-ends receiving the ends of said clamp sections tohold the latter assembled.

4. A trolley wire guard support comprising two elongated clamp sectionshaving outwardly bowed portions between their ends adapted to jointlysurround a trolley wire insulator, and guard-supporting hangers havinglinks at their upper ends receiving the ends of said clamp sections tohold the latter assembled, said ends of said clamp sections beingprovided with lugs preventing accidental movement of said linkstherefrom.

In testimony whereor1 I affix my signature. Y
